Who We Are

We are builders, problem solvers, and perfectionists; operating at the intersection of design and craftsmanship. From custom homes to full-scale renovations, we don’t just transform spaces. We transform the way people live.

Based in Toronto. Built on excellence. Recognized across the industry.

Our Story

Allen Misaghi didn’t build Grand Design Build overnight. He built it the hard way, through relentless dedication, an uncompromising eye for quality, and a refusal to settle for anything less than exceptional.

What started as one man’s pursuit of excellence grew into one of Toronto’s most recognized names in construction and architectural development. Project by project. Client by client. Building by building.

“This isn’t just a company. It’s what never stopping looks like.”

What We Do

Custom homes. Full renovations. Home Additions. Laneway suites. Architectural development.

We take on the projects others won’t. We finish what we start. And we do it at a standard that speaks for itself long after the last nail is driven.

Why Toronto Trusts Us

Over a decade of delivering on our promises. A client list built entirely on referrals, reputation, and results.

We don’t just build structures. We build trust.

We Show Up

On every jobsite. For every client. Through every challenge.

That’s not a slogan. That’s how Grand Design Build was built, and it’s how we operate every single day.
